This standard specifies the general requirements for the energy consumption classification of industrial box type resistance furnaces, including energy consumption parameters, energy consumption range, grade division and test methods. It is suitable for box type resistance furnaces that perform heat treatment such as normalizing, tempering, annealing and quenching on workpieces. Through this standard, the energy consumption level of box type resistance furnaces can be evaluated, and the energy saving improvement and optimal use of equipment can be promoted.
